  • Regiocontrolled Gold-Catalyzed [2+2+2] Cycloadditions of Ynamides with Two Discrete Nitriles to Construct 4-Aminopyrimidine Cores
    作者:Somnath Narayan Karad、Rai-Shung Liu
    DOI:10.1002/anie.201405312
    日期:2014.8.18
    Reported herein is the novel goldcatalyzed intermolecular [2+2+2] cycloaddition of ynamides with two discrete nitriles to form monomeric 4‐aminopyrimidines, which are pharmaceutically important structural motifs. The utility of this new cycloaddition is demonstrated by the excellent regioselectivity obtained using a variety of ynamides and nitriles.

    A Cp*Co(III)-catalyzed [5+2] C–H annulation reaction of 2-vinylphenols with ynamides was developed. The reaction led to the efficient synthesis of valuable 2-aminobenzoxepines in high regioselectivity. Mild reaction conditions, good functional group tolerance, and moderate to good yields were observed. The synthetic utility was demonstrated by a gram-scale synthesis and further transformations of the

  • Zn(II)-Catalyzed One-Pot Synthesis of Coumarins from Ynamides and Salicylaldehydes
    作者:Huen Ji Yoo、So Won Youn
    DOI:10.1021/acs.orglett.9b01181
    日期:2019.5.3
    A highly efficient and straightforward synthesis of diversely substituted coumarins from ynamides and salicylaldehydes in the presence of Zn(II) catalyst has been developed. The sulfonamide moiety of ynamides was successfully recycled in this process, serving as an effective traceless directing group for high regioselectivity in the bond-forming event. The advantages of this protocol are good functional

  • Harnessing the Polarizability of Conjugated Alkynes toward [2 + 2] Cycloaddition, Alkenylation, and Ring Expansion of Indoles
    作者:Tapas R. Pradhan、Hong Won Kim、Jin Kyoon Park
    DOI:10.1021/acs.orglett.8b02230
    日期:2018.9.7
    Reported is the utilization of electronically biased conjugated alkynes in the development of highly diastereo- and regioselective dearomative [2 + 2] cycloadditions, alkenylations, and ring expansions of electron-rich indoles. Regioselective protonations of cross- and linear-conjugated alkynes were found to be crucial for accessing various cyclobutene-fused indoline and alkenylated indole derivatives

  • Gold-Catalyzed [4+2]- and [3+3]-Annulations of Ynamides with 1-Yn-3-ols to Access Six-Membered Carbocycles and Oxacycles <i>via</i> Three Distinct Cyclizations
    作者:Sovan Sundar Giri、Rai-Shung Liu

    日期:2017.10.4
    and 1‐yn‐3‐ols are described; the resulting carbo‐ and heterocycles were produced efficiently in one‐pot operations using a gold catalyst. The chemoselectivities of these annulations are controlled by variations of the substituents of the ynamides and the 1‐yn‐3‐ols. This reaction sequence involves initial alkoxylations of ynamides, followed by Claisen rearrangement of propargylic enol ethers, and ends
    描述了三种不同的催化酰胺和1-yn-3-ols催化环化的策略;在使用催化剂的一锅操作中有效地生产了碳和杂环。这些环空的化学选择性受炔基和1–yn–3–ol取代基的变化控制。该反应顺序包括ynamides的初始烷氧基化,随后炔烯醇醚的Claisen重排,并结束与6-内-三角函数的1-丙二烯基-5-酰胺中间体的环化反应。在这些级联环中,5-烯基-1-酰胺的环化生成5,6-二氢-2-吡喃酮和6-亚烷基环己基-2-烯-1-羧酰胺在文献中是空前的。
